When you are hanging out with friend, whether it is a backyard barbeque or a picnic in the park, music always makes the festivities a little more enjoyable. However, packing a heavy, large speaker into your picnic basket isn’t exactly convenient.

Alpatronix AX400 Bluetooth speaker is less than five inches long and just over two inches tall. So, you can toss it in with all of your other outdoor gear and barely even notice its existence until you are ready to rock the tunes.

The Bluetooth 4.0 connected speaker, which weighs just eight ounces, has a high fidelity stereo sound with a build in rear-facing subwoofer. At only 4.6 inches, it is small enough to fit in the palm of your hand.

The speaker includes a build-in microphone so when you get a phone call, you can use it for speakerphone conversations. The top of the device includes a touch screen with audio playback controls.

You can connect any device with Bluetooth 4.0 support. However, thanks to the 3.5mm jack and included cable, you can also connect to older devices that don’t have Bluetooth.

The ion-lithium battery is supposed to last up to 10 hours. So, a long hike in the woods shouldn’t be a drain on anything but your muscles.

The best part about this mini speaker is the price. It is available on Amazon, where it has received a 4.5 star rating across 1,300 reviews, in a variety of colors, including red, green orange, blue, and black, for $38.
